To all whom it may concern: I

Be it known that I, Wnnnmm ]B AYLEY, citizen ofthe United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certa n new and useful Improvements in Window- Screens for Swingin Sashes, 0t which'thefollowing is a speci cation.

My invention relates to window constructions, of the swinging sash type andmore particularly to the application of fly screens thereto.

The invention as herein shown and described is especially adapted to center p1voted swinging sash or to center "pivoted ventilators and particularly to such ventilators as are found in large window units in factory and auditorium constructions.

It is desirable to provide fly screens for screening window openings particularly in bakery, confectionery, and torium, school i and -residential constructions. lit has heretofore been the custom when attempting to screen a swinging sash window to construct a semicircular inclosure ofscreen material upon the exterior or interior of the window. Such arcuate screen-'inclosures are unsightly in appearance and occupy an excessive amount of space The object of the invention is to simplify the structure as well as the means and mode of operation of such devices, whereby they will not only be cheapened in construction,

but will be more eficient'in use capable of being easily and quickly adjusted, of a pleasingconventional appearance, so arranged as to obviate all interference between the swinging sash and the screen and unlikel to get out of repair. v

further object of the invention is to provide means whereby the screen will maintain constant engagement with the, swinging sash in all. itspositions of angular adjustment. I

With the above primary and other incidental objects inview as will more fullyappear in the specification, the invention consists of the' features of construction, the

. parts and combinations thereof and the mode at operation or their equivalents as hereinalter described and set forth in the claims. ]in thedrawim, Figure 1 .is a perspective sash, such as is commonly or auditorium construction, pivoM ventilator therein used infactory having a "center to which a fly Specification of Letters Patent.

ew of a portion ot av metallic window screen has been applied in accordance with the invention herein described and shown.

Like parts are indicated by similar'char Fatented duly dd, ldld. 'npplimtton filed @ctolhcr at, 1913. crial'Wo. mania.

actors of reference throughout the several I views.

][n the drawmgs 1 is a portion. of a window unit comprising angularly disposed sash bars 2, inwhich are secured panes of glass 3. 'lhe-wlndow unit shown is provided with a center pivoted swinging ventilator sash t,

capable of. oscillatory movement about a transverse medially. disposed axis. The swlngmg sash may be supported onany sultable form of trunnions. Such trunnion or pivotal support forms no part. of the present invention, and therefore has not been illustrated in detail. The sash being centrally supported, its opposite ends swing to and from the top bar 5 and the sillbar 6 of the window opening.

In Figs. 2 and 3 of the drawing, the swinging sash has been shown provided with transversely disposed parallel sash bars 7,

located ad acent to but on opposite sides of the axis of the swinging. sash. Located intermediate the transverse sash bars 7 is a reversed channel bar8 ofsubstantially Z or shaped cross sectional form.

llhe fly screen is dividedinto twoseparate sections, an upper section 9 upon one side of the swinging sash and a lower sec.- tlon uponft e tion with the sash, that the latter in its opening movement will swing away from both screen sections. The screen sections 9 opposite side thereof; These sash sections are so located in relaand 10 are permanently secured in their respective position. I

Carr ed upon the adjacent ed? or the respective screensection are flexi le plates or flangesll proJectinig one toward the other and engaglng the opposite sides of the reversed channel bar 8 adjacent to the axis of the sash as shown in Figs. 2 and 3.. The construction is such that as the sash swings to its open position the flanges or plates 1 are flexed in opposite directions by the rotation at the'reversed channel or d bar. The I the sash.

resiliency of the flexible flanges or plates 11 serves to maintain such plates in constant engagement with the reversed channel or Z bar throughout the full degree of the movement of the window sash. Thisefi'ectually obviates any openingintermediate the sash and. screen at any position in the path of travel of the former. As the sash is returned to its normal position, the flexible plates of .the flanges 11 likewise assume their normal positions as shown in Fig. 2, meanwhile maintaining constant engagement with In Fig. 4 there is shown a modification of the construction in which a pipe or transversetubular member 12 is substituted for the 2 bar 11.' This tubular member is concentric with the axis of oscillation of the sash. The flexible plate or flanges 11 of the screen engage the periphery of the pipe or tubular member. Inasmuch as the tubular member 12 is concentric with the axis of oscillation, it will be noted that no flexing of the flanges or plates 11 will occur upon the oscillation" of the sash. Constant engagement of thefianges or plates 11 with the pipe or tubular members 12 will be maintained by the resilience of the flanges throughout the full degree of adjustmentof the sash to exclude insects and to prevent their entrance between the adjacent edges of the screen sections.

In Fig. 5 there is shown a construction similar to that of Fig. 3 except that in lieu of the flexible plate or flanges 11, carried by the screen section arcuate flanges 13 are provided upon the swinging sash. These areuate flanges 13 are concentric with the axls of oscillation of 'suficient radius to insure their engagement with the adjacent edges of the sash sections throughout the movement of the sash as indicated by dotted lines.

it is obvious that in lieuof the arcuate flanges as shown in.Fig. 5, the anges 13 might be flexible and flat or tan 'ential in relation with the axis of the sash, in whichcase such flanges would yield against the resiliency thereof as the sash is oscillated.

2and 3. A

In Fig. 7 there is shown a further modifi cation embodying a single transverse sash bar It carrying at its opposite edges arcuate flanges 15 concentric with the axis of oscillation and adaptedto engage the edges of the adjacent screen sections. It is obvious that e in lieu of the arcuate flanges 15 as shown,

these flanges may be flat and flexible whereby they will yield to compensate for the ad justment of the sash.

In Fig. 8 is shown a further modification in which the opposite edges of the transyers'e sash bar areeaoh provided with an inturned arcuate fiange 16 concentric with the axis of oscillation. These arcuate flanges 16 engage the adjacent screen sections throughout the full degree of movement of the sash. It is obvious that in lieu of locating thefscreen sections closely adjacent to the arcuate flanges 16 as shown in;

said Fig. 8, the screen sections may be spaced away therefrom and provided with flanges similar to the flanges 11. of Fig. 4-, WlllCh will bear upon the arcuate surfaces of the flanges 16. Such constructionis obvious in view of Fig. 4-.

It will be noted that in. each'of the constructions referred to, there are provided two separated screen units located on opposite sidesof the swinging sash and provided with means for maintaining constant eugagement with the sash throughout all positions of angular adjustment thereof. The sash construction embodying the parallel transverse sash bars located at opposite sides of the axial line of the sash as; herein described, enables the screen flanges 11 to be carriedinto the body of the sash to a position closely adjacent to the axis of oscillation, thus not only improving the appearance of the construction, but enabling the sash to operate with minimum effort and with minimumflexing of the flanges;

While the sash herein shown and described d is of the center pivoted, horizontal axis type,

it is to be understood that the invention is not limited to such construction. The construction herein shown is equally applicable to a sash .ivoted on a vertical axis or to a single lea sash. pivoted adjacent to the edge thereof. In the latter case only a single screen section will be employed.

From the above" description it will be apparent that there is thus provided a device of the character described, possessing the particular features of advantage before enumerated as desirable but which obviously is susceptible of modification in its form, proportion detail construction or arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.

- 'While in. order to comply with the statute,

the invention has been. described in language more or less specific as to certain structural features, it is to be understood that the invention is not limited to any specific details, b t that-the means and construction herein navaaaa described comprise but one mode of putting the invention into efiect and the invention is claimed broadly in any of its possible forms or modifications within the scope of the appended claims.

Having thus described my invention, ll

' claim:

IL. A swinging sash, having a transverse recess therein adjacent to the axis of oscillation, and a screen section to and from which the sash swings projecting within the trans verse recess.

2. In a screen construction for swinging sash windows, a swinging sash, a reversed y from which the corresponding leaves of the sash are oscillated, a substantially 2 shaped contact bar carried by the sash adjacent to the axis of oscillation thereof, and fiem'ble tensioned flanges carried by the screen sections engaging the opposite sides of the bar.
